i am using swift4.2 and Xcode 10 and i am trying to make iOS app uses location service and it gives me exception: Fatal error: Unexpectedly found nil while unwrapping an Optional value
so i tried to check if location returns nil so i copy my code and print location and it returns null , i simulated location in Xcode from product>scheme>edit scheme>default location and checked location in debug area and it simulated to location i choose any one know the problem?
import CoreLocation
class LocationVC: UIViewController,CLLocationManagerDelegate {
let locationManager = CLLocationManager()
var currentlocation:CLLocation!
override func viewDidLoad() {
super.viewDidLoad()
locationManager.delegate = self
locationManager.desiredAccuracy = kCLLocationAccuracyBest
locationManager.requestWhenInUseAuthorization()
locationManager.startMonitoringSignificantLocationChanges()
}
override func viewDidAppear(_ animated: Bool) {
super.viewDidAppear(animated)
authorizelocationstates()
}
func authorizelocationstates(){
if CLLocationManager.authorizationStatus() == .authorizedWhenInUse {
currentlocation = locationManager.location
print(currentlocation)
}
else{
locationManager.requestWhenInUseAuthorization()
authorizelocationstates()
}
}
I have run your code and I just added missing key Privacy - Location When In Use Usage Description in info.plist file.
And I have made some changes in your code and get nil value because method getting called multiple time and when user give permission and method again called and going to print location detail but the fact is stilllocationManager variable has not user location data yet.
get location details in locationManager when delegate didUpdateLocations called
I have done some changes in your code:
import UIKit
import CoreLocation
class ViewController: UIViewController,CLLocationManagerDelegate {
var locationManager = CLLocationManager()
var currentlocation:CLLocation!
override func viewDidAppear(_ animated: Bool) {
super.viewDidAppear(animated)
// authorizelocationstates()
}
func authorizelocationstates(){
if CLLocationManager.authorizationStatus() == .authorizedWhenInUse {
currentlocation = locationManager.location
print(currentlocation)
}
else{
// Note : This function is overlap permission
// locationManager.requestWhenInUseAuthorization()
// authorizelocationstates()
}
}
func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
locationManager = manager
// Only called when variable have location data
authorizelocationstates()
}
override func viewDidLoad() {
super.viewDidLoad()
locationManager.delegate = self
locationManager.desiredAccuracy = kCLLocationAccuracyBest
// Get Location Permission one time only
locationManager.requestWhenInUseAuthorization()
// Need to update location and get location data in locationManager object with delegate
locationManager.startUpdatingLocation()
locationManager.startMonitoringSignificantLocationChanges()
}
}
Hope it will help you.
In iOS geolocation, the code works if the locationManager is declared and initialized separately, however it does not work if it is declared and initialized at the same time. Why is it so? The following is the working code sample:-
var locationManager : CLLocationManager!
func initLocManager() {
locationManager=CLLocationManager()
locationManager.delegate = self
locationManager.desiredAccuracy = kCLLocationAccuracyNearestTenMeters
locationManager.activityType = .automotiveNavigation
locationManager.distanceFilter = 10.0
}
func retrieveLocation(){
initLocManager()
locationManager.requestAlwaysAuthorization()
locationManager.startUpdatingLocation()
}
func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
for location in locations {
print("Long \(location.coordinate.longitude)")
print("Lati \(location.coordinate.latitude)")
}
}
whereas the following code does not work:-
var locationManager = CLLocationManager()
func initLocManager() {
locationManager.delegate = self
locationManager.desiredAccuracy = kCLLocationAccuracyNearestTenMeters
locationManager.activityType = .automotiveNavigation
locationManager.distanceFilter = 10.0
}
func retrieveLocation(){
initLocManager()
locationManager.requestAlwaysAuthorization()
locationManager.startUpdatingLocation()
}
func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
for location in locations {
print("Long \(location.coordinate.longitude)")
print("Lati \(location.coordinate.latitude)")
}
}
Another way:
Create new file with this code:
import UIKit
import CoreLocation
class LocationManager: CLLocationManager, CLLocationManagerDelegate {
static let shared = LocationManager()
public var currentLocation = CLLocation() {
didSet {
NotificationCenter.default.post(name: NSNotification.Name(rawValue: LocationManager.LocationUpdatedNotification), object: self, userInfo: nil)
}
}
static let LocationUpdatedNotification: String = "LocationUpdate"
private override init() {
super.init()
self.delegate = self
self.desiredAccuracy = kCLLocationAccuracyNearestTenMeters
self.activityType = .automotiveNavigation
self.distanceFilter = 10.0
self.requestAlwaysAuthorization()
self.startUpdatingLocation()
}
func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
if let lastLocation = locations.last {
currentLocation = lastLocation
}
}
}
In AppDelegate.swift
_ = LocationManager.shared // Add this line to func didFinishLaunchingWithOptions
Now you can get current user location using this code:
LocationManager.shared.currentLocation
Also you can subscribe for LocationUpdate notification anywhere in your project.
I am trying to use location manager in my application. I set the code as I saw in many posts and examples and everything is working fine, and I get the location manager to show the current location as set in the simulator. I then change the location in the simulator and my app gets the new location.
I then reboot my machine, and restart my application, but the location manager stops working. I tried to change the code from using addObserver() to using didUpdateLocations, and sometimes I manage to restart the location manager to work. But when I reboot the machine it stops working again. I tried resetting the simulator and authorizing again the app to get location updates, but with no success. In all cases my app prints that it has authorization to get location update but it does not work. I also tried cleaning the app and rebuilding it, but with no success.
Below are the 2 versions of the code I use.
CODE with addObserver
class TViewController: UIViewController, GMSMapViewDelegate, CLLocationManagerDelegate {
var myLocation: CLLocation?
var locationManager = CLLocationManager()
#IBOutlet weak var mapView: GMSMapView!
override func viewDidLoad() {
super.viewDidLoad()
locationManager.desiredAccuracy = kCLLocationAccuracyBest;
locationManager.distanceFilter = kCLDistanceFilterNone;
locationManager.delegate = self
locationManager.requestWhenInUseAuthorization()
mapView!.settings.myLocationButton = true
}
// get updates of myLocation
override func observeValueForKeyPath(keyPath: String?,
ofObject object: AnyObject?,
change: [String : AnyObject]?,
context: UnsafeMutablePointer<Void>)
{
myLocation = change![NSKeyValueChangeNewKey] as? CLLocation
print("in newlocation = \(myLocation)")
}
func locationManager(manager: CLLocationManager, didChangeAuthorizationStatus status: CLAuthorizationStatus) {
if status == CLAuthorizationStatus.AuthorizedWhenInUse {
print("in myLocation is authorized")
locationManager.startUpdatingLocation()
mapView!.myLocationEnabled = true
mapView!.addObserver(self, forKeyPath: "myLocation", options: NSKeyValueObservingOptions.New, context: nil)
}
}
}
CODE with didUpdateLocations
extension TViewController: CLLocationManagerDelegate {
func locationManager(manager: CLLocationManager, didChangeAuthorizationStatus status: CLAuthorizationStatus) {
if status == .AuthorizedWhenInUse {
print("in myLocation extension is authorized")
isLocationAvailable = true
locationManager.startUpdatingLocation()
mapView.myLocationEnabled = true
mapView.settings.myLocationButton = true
}
}
func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
myLocation = locations.first
print("in newlocation extension = \(myLocation)")
mapView.camera = GMSCameraPosition(target: myLocation!.coordinate, zoom: 15, bearing: 0, viewingAngle: 0)
}
class TViewController: UIViewController, GMSMapViewDelegate {
var myLocation: CLLocation?
var locationManager = CLLocationManager()
#IBOutlet weak var mapView: GMSMapView!
override func viewDidLoad() {
super.viewDidLoad()
locationManager.desiredAccuracy = kCLLocationAccuracyBest;
locationManager.distanceFilter = kCLDistanceFilterNone;
locationManager.delegate = self
locationManager.requestWhenInUseAuthorization()
mapView!.settings.myLocationButton = true
}
This is my code:
import Foundation
import CoreLocation
class ViewController: UIViewController, CLLocationManagerDelegate {
let locationManager = CLLocationManager()
#IBOutlet weak var locationLabel: UILabel!
var coord: CLLocationCoordinate2D?
override func viewDidLoad() {
super.viewDidLoad()
locationManager.delegate = self
locationManager.desiredAccuracy = kCLLocationAccuracyBest
locationManager.requestWhenInUseAuthorization()
if CLLocationManager.authorizationStatus() == CLAuthorizationStatus.Authorized {
locationManager.startUpdatingLocation()
println(coord!.longitude)
locationLabel.text = "location found"
}
func locationManager(manager: CLLocationManager!, didUpdateLocations locations: [AnyObject]!) {
var locationArray = locations as NSArray
var locationObj = locationArray.lastObject as CLLocation
coord = locationObj.coordinate
}
}
}
This code does not return anything (it should print the longitude). Which seems O.K because if I move
locationManager.startUpdatingLocation()
println(coord!.longitude)
out of the if statement, Xcode throws a runtime error and says it unexpectedly found nil while unwrapping an Optional value. I do not understand why though? The systems asks me permission to use my location fine.
Thanks!
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
locationManager = CLLocationManager()
locationManager.delegate = self
locationManager.desiredAccuracy = kCLLocationAccuracyBest
locationManager.requestAlwaysAuthorization()
locationManager.startUpdatingLocation()
}
func locationManager(manager:CLLocationManager, didUpdateLocations locations:AnyObject[] {
println("locations = \(locations)")
gpsResult.text = "success"
}
Are you running on iOS8? Assuming so:
1.You need to initialize
self.locationManager = CLLocationManager()
2.Right after, call self.locationManager.requestAlwaysAuthorization(); (before self.locationManager.delegate = self )
3.Add these keys to Info.plist, using an external text editor (change the texts accordingly)
<key>NSLocationWhenInUseUsageDescription</key>
<string>This is needed for iOS8 and up (when in use)</string>
<key>NSLocationAlwaysUsageDescription</key>
<string>This is needed for iOS8 and up (always)</string>
4.The place where you call println(coord!.longitude) may be too early. Move it into the locationManager function.
Then it should display an alert asking for permission for using location services.
I am trying to convert an old app in ObjC to Swift as a practice exercise and have ran in to some issues. The way I had it in the old app, it was establishing the CLLocation Manager and then I would use:
manager = [[CLLocationManager alloc]init];
manager.delegate = self;
manager.desiredAccuracy = kCLLocationAccuracyBest;
[manager startUpdatingLocation]
which would call automatically:
-(void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation{
}
and from there I could extract all the information I needed. But in swift, there is no autocompletion of this method and I cannot figure out how to reproduce it. The documentation says that
startUpdatingLocation()
will still be called by the delegate, but it isn't happening.
This is what I have so far:
import UIKit
import corelocation
class ViewController: UIViewController,CLLocationManagerDelegate{
#IBOutlet var gpsResult : UILabel
var manager:CLLocationManager!
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
manager = CLLocationManager()
manager.delegate = self
manager.desiredAccuracy = kCLLocationAccuracyBest
manager.startUpdatingLocation()
}
func locationManager(manager:CLLocationManager, didUpdateLocations locations:AnyObject[]) {
println("locations = \(locations)")
gpsResult.text = "success"
}
}
Any help or pointers on where to look would be appreciated. Thanks.
EDIT: Updated from Suggestions, but still not working
EDIT2: Seems to be some bug not allowing the method to work properly in the ViewController
You are missing two things. First, you have to ask for permission using requestAlwaysAuthorization or requestWhenInUseAuthorization(). So your viewDidLoad() should be like this:
var locationManager = CLLocationManager()
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
locationManager.delegate = self
locationManager.desiredAccuracy = kCLLocationAccuracyBest
locationManager.requestAlwaysAuthorization()
locationManager.startUpdatingLocation()
}
Second, edit your Info.plist as indicated here.
First add this two line in plist file
NSLocationWhenInUseUsageDescription
NSLocationAlwaysUsageDescription
Then this is class working complete implement this
import UIKit
import CoreLocation
#UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate, CLLocationManagerDelegate {
var window: UIWindow?
var locationManager: CLLocationManager!
var seenError : Bool = false
var locationFixAchieved : Bool = false
var locationStatus : NSString = "Not Started"
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: NSDictionary?) -> Bool {
initLocationManager();
return true
}
// Location Manager helper stuff
func initLocationManager() {
seenError = false
locationFixAchieved = false
locationManager = CLLocationManager()
locationManager.delegate = self
locationManager.locationServicesEnabled
locationManager.desiredAccuracy = kCLLocationAccuracyBest
locationManager.requestAlwaysAuthorization()
}
// Location Manager Delegate stuff
// If failed
func locationManager(manager: CLLocationManager!, didFailWithError error: NSError!) {
locationManager.stopUpdatingLocation()
if (error) {
if (seenError == false) {
seenError = true
print(error)
}
}
}
func locationManager(manager: CLLocationManager!, didUpdateLocations locations: AnyObject[]!) {
if (locationFixAchieved == false) {
locationFixAchieved = true
var locationArray = locations as NSArray
var locationObj = locationArray.lastObject as CLLocation
var coord = locationObj.coordinate
println(coord.latitude)
println(coord.longitude)
}
}
// authorization status
func locationManager(manager: CLLocationManager!,
didChangeAuthorizationStatus status: CLAuthorizationStatus) {
var shouldIAllow = false
switch status {
case CLAuthorizationStatus.Restricted:
locationStatus = "Restricted Access to location"
case CLAuthorizationStatus.Denied:
locationStatus = "User denied access to location"
case CLAuthorizationStatus.NotDetermined:
locationStatus = "Status not determined"
default:
locationStatus = "Allowed to location Access"
shouldIAllow = true
}
NSNotificationCenter.defaultCenter().postNotificationName("LabelHasbeenUpdated", object: nil)
if (shouldIAllow == true) {
NSLog("Location to Allowed")
// Start location services
locationManager.startUpdatingLocation()
} else {
NSLog("Denied access: \(locationStatus)")
}
}
}
I'm not sure why, but it seems like startUpdatingLocation isn't presenting the user prompt on the iOS 7 simulator, but when I enabled it manually it worked as expected if I used the newer form of the delegate method:
var manager:CLLocationManager!
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
manager = CLLocationManager()
manager.delegate = self
manager.desiredAccuracy = kCLLocationAccuracyBest
manager.startUpdatingLocation()
}
func locationManager(manager:CLLocationManager, didUpdateLocations locations:[AnyObject]) { // Updated to current array syntax [AnyObject] rather than AnyObject[]
println("locations = \(locations)")
}
The format you're using has been deprecated since iOS 5 or 6, so apparently it's not supported at all by the swift bridging layers.
had the same issue. didUpdateLocations - was not working. Run your app. Go to the Settings page -> Privacy -> Location and turn off Location Services. didFailWithError will catch the error about absent Location Services. Then turn it on. Since that moment didUpdateLocations will catch locations.
Here is my very simple code that works:
first add Core Location framework in General/Linked Frameworks and Libraries
then add following into Info.plist:
<key>NSLocationWhenInUseUsageDescription</key>
<string>blablabla</string>
<key>NSLocationAlwaysUsageDescription</key>
<string>blablabla</string>
this is my ViewController.swift file:
import UIKit
import CoreLocation
class ViewController: UIViewController, CLLocationManagerDelegate {
var locationManager:CLLocationManager!
override func viewDidLoad() {
super.viewDidLoad()
locationManager = CLLocationManager()
locationManager.delegate = self
locationManager.desiredAccuracy = kCLLocationAccuracyBest
locationManager.requestAlwaysAuthorization()
locationManager.startUpdatingLocation()
}
func locationManager(manager:CLLocationManager, didUpdateLocations locations: [CLLocation]) {
print("locations = \(locations)")
}
}
For Swift 3
import UIKit
import CoreLocation
class ViewController: UIViewController,CLLocationManagerDelegate {
var locationManager:CLLocationManager!
override func viewDidLoad() {
super.viewDidLoad()
locationManager = CLLocationManager()
locationManager.delegate = self
locationManager.desiredAccuracy = kCLLocationAccuracyBest
locationManager.requestAlwaysAuthorization()
locationManager.startUpdatingLocation()
// Do any additional setup after loading the view, typically from a nib.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
func locationManager(_ manager:CLLocationManager, didUpdateLocations locations: [CLLocation]) {
print("locations = \(locations)")
}
}
I hope there are two ways.
var locationManager: CLLocationManager = CLLocationManager()
var initialLocation :CLLocation?
var updatedUserLocation :CLLocation?
override func viewDidLoad() {
super.viewDidLoad() {
//MapView Location
locationManager.delegate = self
locationManager.desiredAccuracy = kCLLocationAccuracyNearestTenMeters
locationManager.requestWhenInUseAuthorization()
locationManager.startUpdatingLocation()
locationManager.startUpdatingHeading()
}
Implementing CLLocationManagerDelegate :
//CLLocationManager Delegate
func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
// This only works when user location is updated.
gpsProviderStatusLabel.changeStatusToOn(gpsProviderStatusLabel)
}
func locationManager(manager: CLLocationManager, didFailWithError error: NSError) {
//Error indicates GPS permission restricted
gpsProviderStatusLabel.changeStatusToOff(gpsProviderStatusLabel)
//Initial Location
initialLocation = locations.first
//Getting Updated Location
updatedUserLocation = locations.last
}
Checking CLLocationDelegate Authorization:
func locationManager(manager: CLLocationManager, didChangeAuthorizationStatus status: CLAuthorizationStatus) {
//This method does real time status monitoring.
switch status {
case .NotDetermined:
print(".NotDetermined")
break
case .AuthorizedAlways:
print(".AuthorizedAlways")
gpsProviderStatusLabel.changeStatusToOn(gpsProviderStatusLabel)
break
case .Denied:
print(".Denied")
gpsProviderStatusLabel.changeStatusToOff(gpsProviderStatusLabel)
break
case .AuthorizedWhenInUse:
print(".AuthorizedWhenInUse")
gpsProviderStatusLabel.changeStatusToOn(gpsProviderStatusLabel)
break
case .Restricted:
print(".Restricted")
break
default:
print("Unhandled authorization status")
break
}
}
Note: changeStatusToOn or changeStatusToOff is a UILabel Extenion method which makes the Label text On/Off with Green/Red Colors.
don't forget to add
NSLocationWhenInUseUsageDescription or
NSLocationAlwaysUsageDescription
in your configuration file (target/Info/custom iOS target properties
Add bellow 2 property in info.plist
NSLocationWhenInUseUsageDescription : Location information is used for fraud prevention
Privacy - Location Usage Description : Location information is used for fraud prevention
If you want to get the user location updated by default, without clicking 'Simulate location' everytime, go to
YourProject-->Build Phases-->Link Binary with libraries-->Add corelocation.framework
The location gets updated automatically/by default when you run the app in the simulator. Tested and works in Swift 2 !
This will ask for permission and track if given permission else quit with an alert. Stops tracking on back button press.
